Malignant glomus tumor in pleural cavity
Glomus tumors, an uncommon hypervascular tumor, arise from modified smooth muscle cells of the glomus body that plays a significant role in the regulation of skin circulation. The tumors are usually located in the extremities, typically in the subungual region of the fingers. Primary glomus tumors of the chest are extremely rare, and to our knowledge, there are no cases have been described in thoracic cavity to date. We here report a case of intrathoracic glomus tumor in a 31-year-old man who presented with a persistent chest pain. Chest computed tomography scans demonstrated an irregularly shaped mass in the left thorax. Left thoracotomy was performed under the suspicious diagnosis of unexplained thorax tumor, and a tumor located in the left upper portion of thorax was founded. Complete resection of tumor along with the partial structure of chest wall was performed. Postoperative diagnosis was malignant glomus tumor.
